Application Connect Failure - x509: certificate signed by unknown authority

Hello everyone,

One of our devs is trying to monitor an application in go lang running on Amazon ECS.
We have done the ‘add data’ process, deployed the application to AWS but are getting the error below on the container logs.

{“level”:“warn”,“ts”:“2022-11-24T11:19:20.168Z”,“caller”:“nrzap@v1.0.1/nrzap.go:31”,“msg”:“application connect failure”,“service”:“account-monitoring”,“error”:“Post “”: x509: certificate signed by unknown authority”}

I’m not really sure which certificate is this and how to resolve this issue, is anyone able to help, please?

Solved by adding the line below to my Dockerfile.

COPY --from=build-env /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/
